FIELD OF THE INVENTION

The present invention generally relates to life jackets, and moreparticularly to an improved structure of a life jacket having a hangingdevice and an inflating device concurrently.

BACKGROUND OF THE INVENTION

Life jacket, regardless of its application in airplanes, ships andferries, or fire squads, rescue centers and mountain climbing, generallyhave some problems related to its shape, function and material. Forinstance, the weight of a life jacket is a burden, and the large volumeof the life jacket makes the storage and carrying difficult. As aresult, users are unwilling to use or carry the life jacket as requiredby regulations, and there is potential risk for safety.

To prevent accidents, manufacturers attempt to enhance the usability ofthe life jacket, so that users are willing to carry and use the lifejacket. In view of the aforementioned urgent need, the inventor of thepresent invention based on years of experience in the related industryto conduct extensive researches and experiments, and finally developedan improved foldable and rollable life jacket made of a thin, light,water-proof and wind-proof material and having a hanging device and aninflating device connected to a life jacket body.

BRIEF SUMMARY OF THE INVENTION

Therefore, it is a primary objective of the present invention to providean improved life jacket structure connected to a hanging device and aninflating device, not only allowing users to inflate the life jacket,but also making the carrying of the life jacket easy.

The life jacket structure comprises a life jacket body, at least one setof hanging devices, a blowing tube and an inflation starting device, andthe life jacket body is made of a light, thin, water-proof andwind-proof material and has the foldable, rollable and deformablefeature, and an internal side of the life jacket body is sewed to forman inflatable airbag, and the life jacket further includes a pair ofstrap holes disposed at corresponding positions on both lateral sides ofthe life jacket body.

The set of hanging devices has two ends, wherein the first end islinearly fixed into the first hanging hole of the life jacket, and thesecond end is linearly fixed into the second hanging hole of the lifejacket. The set of hanging devices further includes two connectingelements and an adjusting element, and a connecting element is installedseparately on both ends of the hanging device and corresponding to thestrap hole of the life jacket, such that the hanging device is coupledwith the life jacket. The adjusting element is provided for adjustingthe length of the hanging device.

The blowing tube is installed at an appropriate position of the lifejacket body and penetrated through the life jacket into the inflatableairbag, such that air is blown into the inflatable airbag through theblowing tube to inflate the inflatable airbag.

The inflation starting device is also installed on the life jacket bodyand disposed on the same side of the blowing tube. The inflationstarting device includes an inflation cylinder and a starting mechanismcoupled with each other, and the starting mechanism includes a pull ringprovided for a user to pull and provide to a start signal the startingmechanism to start inflating the life jacket by the inflation cylinder.

To make it easier for our examiner to understand the technicalcharacteristics and effect of the present invention, we use preferredembodiments with accompanying drawings for the detailed description ofthe invention. However, the embodiments and drawings are provided forillustrating the invention, but not intended for limiting the scope ofthe invention.

DETAILED DESCRIPTION

With reference to FIG. 1 for a life jacket structure in accordance witha preferred embodiment of the present invention, the life jacket 10comprises a life jacket body 100, a hanging strap 200, a blowing tube300 and an inflation starting device 400. The life jacket body 100 ismade of a thin, light, water-proof and wind-proof material, and foldableand rollable easily. An internal side of the life jacket body 100 issewed into an inflatable airbag 110, such that air can be blown throughthe blowing tube 300 to start the inflation starting device 400 andallow air to enter into the inflatable airbag 110 for the use of thelife jacket 10.

The life jacket body 100 further includes two hanging holes 120, 130disposed at appropriate positions on both sides of the life jacket body100 according to the actual requirement.

The hanging strap 200 has two distal surfaces 210, 220, coupled to thehanging holes 120, 130 of the life jacket body 100 through twoconnecting elements 230, 240 respectively. The hanging strap 200 furtherincludes an adjusting element 250 for adjusting the length of thehanging strap 200.

The blowing tube 300 is installed at an appropriate position on thefront side of the life jacket body 100 and penetrated through the lifejacket body 100 into the inflatable airbag 110, so that a user can blowair into the inflatable airbag 110 through the blowing tube 300 toinflate the inflatable airbag 110.

The inflation starting device 400 is installed at an appropriateposition of the front side of the life jacket body 100, and similarlypenetrated through the life jacket body 100 into the inflatable airbag110. The inflation starting device 400 includes an inflation cylinder410, a starting device 420 and a pull ring 430. The starting device 420is coupled to the inflation cylinder 410, and the pull ring 430 isextended from the interior of the starting device 420 to the outside andprovided for its use by the user.

If the user pulls the pull ring 430, the pull ring 430 will provide astart signal to the starting device 420. After the starting device 420receives the start signal, the inflation cylinder 410 will be turned onto inflate the life jacket body 100.

With reference to FIGS. 2 to 5 for schematic views of a user wearing alife jacket in accordance with a preferred embodiment of the presentinvention, the life jacket body 100 is made of a thin, light,water-proof and wind-proof material and has an easily foldable androllable feature, the hanging strap 200 can be used for wearing the lifejacket 10 from the neck to the body of the user as shown in FIG. 2, orthe life jacket 10 is rolled and wrap the hanging strap 200 around theuser's arm as shown in FIG. 3, or the life jacket 10 is rolled andfolded to reduce the volume and allow the user to hang the life jacket10 on the user's wrist easily by the hanging strap 200 as shown in FIG.4 according to different needs of the user.

As shown in FIG. 4 or FIG. 5, the life jacket 10 is hanged at the user'swaist or chest by the hanging strap 200. Regardless of the storagemethod, it is necessary to make sure that the blowing tube 300 and theinflation starting device 400 are protruded out from the life jacketbody 100 and coupled to the inflatable airbag 110 in the life jacketbody 100, such that the user can take off and use the life jacket 10easily.
